New regulations for the installation of instant water heaters will be issued in 2025, and professional installation will become a mandatory requirement

The new standard for the installation of thermal water heaters requires that they must be installed by certified professionals and specifies the installation acceptance criteria for the first time

The Ministry of Housing and Urban-Rural Development has issued the latest "Instantaneous Water Heater Installation Specifications", which will be implemented on January 1, 2026. The new regulations require that installation must be carried out by personnel with electrician certificates and professional qualifications, and specify that the circuit must be ≥6 square millimeters and the water circuit must adopt double leak-proof standards. An acceptance form must be provided after installation, and products that are not installed in accordance with regulations will not be covered by warranty. It is estimated that the new regulations will create 100,000 professional installation positions, and consumers can verify the installation qualifications by scanning the QR code on the body. It is recommended to choose a merchant who provides formal installation services when purchasing, and keep complete receipts.
